Hurricane Frances (1986)
Hurricane Frances was the second most intense tropical cyclone in the Atlantic during 2004 and proved to be very destructive in Florida. It was the sixth named storm, the fourth hurricane, and the third major hurricane of the 2004 Atlantic hurricane season. The system crossed the open Atlantic in late August, moving to the north of the Lesser Antilles while strengthening. Its outer bands struck Puerto Rico and the British Virgin Islands while passing north of the Caribbean Sea. The storm's maximum sustained winds peaked at , achieving Category 4 on the Saffir-Simpson Hurricane Scale. As the system's forward motion slowed, the eye passed over San Salvador Island and very close to Cat Island in the Bahamas. Frances was the first hurricane to impact the entire Bahamian archipelago since 1928 and almost completely destroyed their agricultural economy. Frances then passed over the central sections of Florida, three weeks after Hurricane Charley, causing significant damage to the ...

Hurricane Charley
Hurricane Charley was the first of four separate hurricanes to impact or strike Florida during 2004, along with Frances, Ivan and Jeanne, as well as one of the strongest hurricanes ever to strike the United States. It was the third named storm, the second hurricane, and the second major hurricane of the 2004 Atlantic hurricane season. Charley lasted from August 9 to 15, and at its peak intensity it attained winds, making it a strong Category 4 hurricane on the Saffir–Simpson scale. It made landfall in Southwest Florida at maximum strength, becoming the strongest hurricane to hit the United States since Hurricane Andrew struck Florida in 1992 and tied with Hurricane Ian as the strongest hurricane to hit southwest Florida in recorded history. After moving slowly through the Caribbean, Charley crossed Cuba on Friday, August 13, as a Category 3 hurricane, causing heavy damage and four deaths. That same day, it crossed over the Dry Tortugas, just 22 hours after Trop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eyewall Replacement Cycle
In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones with maximum sustained winds greater than , or hurricane-force, and particularly in major hurricanes of Saffir–Simpson scale, Saffir–Simpson category 3 to 5. In such storms, some of the outer rainbands may strengthen and organize into a ring of thunderstorms—a new, outer Eye (cyclone), eyewall—that slowly moves inward and robs the original, inner eyewall of its needed moisture and angular momentum. Since the strongest winds are in a tropical cyclone's Eye (cyclone), eyewall, the storm usually weakens during this phase, as the inner wall is "choked" by the outer wall. Eventually the outer eyewall replaces the inner one completely, and the storm may re-intensify. The discovery of this process was partially responsible for the end of the U.S. government's hurricane modification experiment Project Stormfury. This project set out to cloud seeding, seed ...

Hurricane Frances From The ISS - 10AM
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

Eye (cyclone)
The eye is a region of mostly calm weather at the center of a tropical cyclone. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds of the cyclone occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is where the barometer reading is lowest. Structure A typical tropi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Shear
Wind shear (; also written windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subtropical Ridge
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as subtropical ridges or highs. It is a high-pressure area at the divergence of trade winds and the westerlies. Etymology A likely and documented explanation is that the term is derived from the "dead horse" ritual of seamen (see Beating a dead horse). In this practice, the seaman paraded a straw-stuffed effigy of a horse around the deck before throwing it overboard. Seamen were paid partly in advance before a long voyage, and they frequently spent their pay all at once, resulting in a period of time without income. This period was called the "dead horse" time, and it usually lasted a month or two. The seaman's ceremony was to celebrate having worked off the "dead horse" debt. As west-bound shipping from Europe usually reached the subtropics at about the time the "dead horse" was worke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Africa
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including Geography of Africa, geography, Climate of Africa, climate, corruption, Scramble for Africa, colonialism, the Cold War, and neocolonialism.

Hurricane Beulah
Hurricane Beulah was an intense Category 5 hurricane which impacted the Greater Antilles, Mexico, and Texas in September 1967. The second tropical storm, second hurricane, only major hurricane, and strongest storm in the 1967 Atlantic hurricane season, Beulah tracked through the Caribbean, struck the Yucatán Peninsula of Mexico as a major hurricane, and moved west-northwestward into the Gulf of Mexico, briefly becoming a Category 5 hurricane. The hurricane made landfall just north of the mouth of the Rio Grande as a Category 3 hurricane. It spawned 115 tornadoes across Texas, which established a new record for the highest amount of tornadoes produced by a tropical cyclone. Due to its slow movement over Texas, Beulah led to significant flooding. Throughout its path, at least 59 people were killed and total damage reached $234.6 million (1967 USD), of which $200 million occurred in the United States, $26.9 million occurred in Mexico, and $7.65 million occurred in the eastern ...
